Embodiment

[0030] Such as figure 1 , figure 2 As shown, the all-refractory structure supports the lattice brick furnace body structure, including the furnace bottom plate 1, the upper surface of the furnace bottom plate 1 is a square pillar 3 built with refractory bricks, and the heat-resistant concrete 2 is poured between the square pillars 3. The concrete 2 and the square pillar 3 form an integral body, the upper surface of the square pillar 3 is a masonry refractory primary arched beam, and the upper surface of the primary arched beam is a masonry secondary arched beam of refractory material along the vertical direction of 90°. The transition brick 8 is placed on the secondary arch beam, and the checker brick 9 is placed above the transition brick 8.

[0031] The primary arched beam is transversely connected and consists of arched bricks 4 and arched protective bricks 5 built on the arched bricks. The arched bricks 4 are naturally wedged tightly in the radial direction, and bosses ...

Abstract

The invention relates to a full-refractory structure-supported checker brick furnace body construction and a construction technology method thereof. According to the method, a double-layer arch-shaped structure is adopted to ensure that a supporting system has enough strength so as to support an upper checker brick heat accumulator, and realize the effective engagement of the upper heat-accumulation checker bricks and a lower arc-shaped cross beam through transition bricks having a special structure, so that not only can the stability of the overall structure be guaranteed, but also the complete communication of all check brick holes of the heat accumulator can be realized; compared with a traditional brick heat accumulator, the full-refractory structure-supported checker brick furnace body construction has the advantages that the unit heat accumulation area is increased by almost one time, and the heat accumulation capability can be improved by 20%. The full-refractory structure-supported checker brick furnace body construction has the most advantage that the refractory supporting structure of checker bricks has high temperature resistance performance, with the refractoriness achieving 1500DEG C, thus completely meeting the special requirement of a heating furnace in a petrochemical industry on burning accumulated carbon below a grate with open fire, and simultaneously meeting the requirements of improving smoke temperature for preheating air and coal gas in the metallurgy industry.

Description

technical field [0001] The invention relates to a high-temperature hot blast stove and a heating furnace structure, in particular to a lattice brick furnace body structure supported by an all-refractory structure and a masonry process. Background technique [0002] At present, alloy cast iron furnace grates, beams and pillars are commonly used in heating furnaces in the metallurgical industry and petrochemical industry to support the checker brick regenerator. The cast iron support method has strict restrictions on the flue gas temperature, that is, the flue gas temperature must be lower than 400°C. Therefore, it has limitations. [0003] The heating furnace in the petrochemical industry is more serious in the low-temperature area of ​​the grate, and it is necessary to burn the carbon deposits and coke with an open flame every year. The grates, beams and pillars made of alloy cast iron must be strictly controlled when they are scorched and burned. When the temperature is lo...
